New Results of SNR Estimation for High-order Modulation
The Cramer-Rao Lower Bounds (CRLB), Data-aided maximum-likelihood (ML) Signal-to-Noise Ratio (SNR) estimation algorithm (DAML), Decision-Directed ML SNR estimation algorithm (DDML) and an iterative ML SNR estimation algorithm for QAM signals are presented in this paper. The performance analysis, computer simulation and performance comparing with another blind SNR estimation algorithm 10, 11 and CRLB are completed. And then the corresponding conclusions are derived.
